我正在尝试做的是调整我的自定义ListView适配器,以使用Picasso库从Web获取的图像.我相信我已经更改了适配器以接受来自毕加索的图像,但我不确定如何使用ListView更改我的实现以接受它.我相信我必须访问holder.imageIcon,但我不知道如何让它运行起来.我的代码如下.

History.java

public class History {
    public String score;
    public String gametype;
    public Picasso icon;

    public History() {
        super();
    }

    public History(String score, String gametype, Picasso icon) {
        super();
        this.score = score;
        this.gametype = gametype;
        this.icon = icon;
    }
}

HistoryAdapter.java

public class HistoryAdapter extends ArrayAdapter<History> {

    Context context;
    int layoutResId;
    History data[] = null;

    public HistoryAdapter(Context context, int layoutResId, History[] data) {
        super(context, layoutResId, data);
        this.layoutResId = layoutResId;
        this.context = context;
        this.data = data;
    }

    @Override
    public View getView(int …

我在从URL接收JSON数组时遇到问题.我已经验证我的链接正常,并且返回了正确的JSON数组,它甚至显示在错误消息中.我不确定这意味着什么.

错误:

码:

    JSONArray jsonArray = jsonArrayParser.getJSONFromUrl(url2);
    JSONArray leagueArray = new JSONArray(jsonArray);
    summary.rTier = leagueData.getString("tier"); …

我已将这行代码添加到我的程序中:

icon1.setImageResource(getResources().getIdentifier(item1, "drawable", getApplicationContext().getApplicationInfo().packageName));

并将图像(.png)添加到我的drawable文件夹中.当我编译时,我收到以下错误:

Error:(773, 32) error: <identifier> expected
Error:(773, 37) error: illegal start of type

R.java中的错误位置:

public static final class drawable {
        public static final int 1001=0x7f020000;
        public static final int 1004=0x7f020001;
        public static final int 1006=0x7f020002;
        public static final int 1011=0x7f020003;
        public static final int 1018=0x7f020004;
        public static final int 1026=0x7f020005;
        public static final int 1027=0x7f020006;
        ..........

每个人都会抛出一对错误.

我将图像放入/ res/drawable-hdpi文件夹中.问题是文件名都是数字的(例如1023.png)吗？

可能是什么原因造成的？

我在获取此信息时遇到问题.我不知道如何访问它.我目前的代码片段如下所示.随意批评那里已经存在的问题.谢谢.

DIR *directory;
struct dirent *fileEntry; 

directory = opendir(argv[1]);
if(directory != NULL)
 {
  while((fileEntry = readdir(directory)) != NULL)
   {
    int i = 0;
    char *filename[];
    filename[i] = fileEntry -> d_name; // Get filename
    // Get inode here
    // Get hard link count here
    i++; 
   }
  }
